ERROR_DS_INAPPROPRIATE_MATCHING
ERROR_DS_INAPPROPRIATE_MATCHING (0x0000202E) is an Active Directory Domain Services LDAP result. The LDAP filter requested a matching rule that is not valid for the target attribute syntax.
What to check
- Verify that the filter operator is supported for the attribute being searched.
- Check whether the client uses an extensible match rule, substring filter, or ordering comparison that the attribute does not support.
- Test the filter with a simple equality expression before adding complex matching logic.
